How do I fix if I can't access server with ssh?

I got a problem not sure how its come from but this its what linode response

I first reviewed the host where your Linode resides for any evidence of resource contention or other similar reports on this host, however my search did not find any resource contention and we have not received any similar reports of issues from this host. With no issues detected on the host level I then reviewed the Linode for any signs of issues we can help you diagnose. On your Linodes 2nd most recent boot I found the following messages in the console:

[10287880.908776] Out of memory: Killed process 1869555 (apache2) total-vm:1798952kB, anon-rss:1202876kB, file-rss:0kB, shmem-rss:0kB, UID:33 pgtables:2732kB oom_score_adj:0

When a server is running out of memory, it can cause a lot of problems, including networking issues. It's possible that you weren't able to access your server because the SSH services was later killed or didn't have enough memory to operate.

You'll want to follow the instructions here for dealing with a server that's running out of memory:

Once you take care of the memory issue, you can then see if there are still additional problems that need to be addressed. Make sure you take steps to restart any services that may have failed and may not be enabled. This guide will help with that:
